Chemical modification of crystal-like mesoporous phenylene-silica with amino group.
نویسندگان
چکیده
Amination of phenylene moieties in crystal-like mesoporous silica hybridized with phenylene is successfully achieved with close to 28% conversion of phenylene by a two-step chemical transformation process while preserving both the ordered mesostructure and crystal-like molecular scale periodicity of the parent material.

Mesoporous silica nanoparticles with unique structure (SBA-15) were synthesized and modified by [3-(2-Aminoethylamino) propyl] trimethoxysilane (AEAPTMS). The synthesized nanoparticles were characterized by TGA, N2 adsorption, SEM, FTIR, CHN elemental analysis. The total weight loss for the modified SBA-15 is 15.2% and thermal analysis reveal...
متن کاملAlkyl surface modification of nanoporous silica SBA-15 by click chemistry to obtain triazole products
In this study, Santa Barbara Amorphous (SBA-15) mesoporous silica has been functionalized with aminopropyl groups that were converted to propargyl-bearing moieties through the reaction with propargyl bromide. The material then underwent an efficient Cu(I)-catalyzed azide alkyne click reaction with sodium azide in order to obtain the corresponding triazole products. The covalent modification of ...
